I'm thinking about buing this motor from a guy wanted to see what everyone's opions would be, all it needs is a intake and tb, what would make the most power and how much do u think it would make through a m6 and 10 bolt with 4.10's? Thanks for any help!!! Here is the specs



Morel solid lifters
248/254 .694/.697 112lsa solid roller Comp cam
Comp High Tech pushrods
10.6 : 1 compression
Katech ported oil pump

Heads:
317 castings, for 4.030 bore
2.080 Ferrea Competition series intake valves
1.600 Ferrea Competition series exhaust valves
Isky Gold Stripe 1.550'' dual springs w/ damper
CV products super7 retainers/locks
GM valve seals
Jesel J2K Mohawk rockers w/ custom 1 piece shims
C5R valve covers

 

The lower end sounds good, however I would go with different heads. Thats quite an investment into a set of 317 heads. Would go with higher compression.

ET heads come with solid roller spring pocket, or even All pro heads, many have used PSI 1224 spring in solid roller LS setups.

Maybe AFR 235 heads will have a solid roller spring pocket?

hate telling people to spend money but I would expect a set of 317 heads setup for solid roller will run you in excess of $2,000.

I do have a set of valve covers that look like factory, however they are raised 1/2" and have coil pack bolts holes in em, if anyone is interested.

 

So what heads should I look for and intake/tb? vic jr, fast??

 

This is a complete motor less intake and tb, those heads are already on it, thanks

 

i am considering a solid roller 370 now..i have a set of dart 225s already...im wanting to see some numbers from other people first though

 

No reason why it should break 500 through a 6 speed. Even an A4 should be upthere.

 

I don't know what your goals are for the car but that is a pretty good size cam for a street car. Like was said above I would squeeze more compression out of it.
